When I was in college, I noticed that I was allowed to use 3 credits of physical education towards my elective credits. However, none were offered at the school, so I took yoga at a community college and transferred the credits in.
I did the same thing. I could take Chicano studies, Asian American studies, African American Studies, or three Karate classes to fulfill a requirement. The first three options were known to be difficult but not particularly deep and students alleged that you would get a bad grade if your political views didn't match the professors' views. I took the latter most option and had way more fun.
Turns out I discovered I really like yoga. :)
